Description

Technical Field

[0001] This utility model relates to the field of lifting clamp technology, and in particular to a lifting clamp with protective function. Background Technology

[0002] In the glass production and processing process, large glass sheets are often cut into smaller pieces, and then the smaller pieces are moved to designated positions using hoisting fixtures to facilitate further processing of the glass and greatly reduce the labor intensity of the workers.

[0003] A patent document with publication number CN219116960U discloses a triangular glass plate lifting clamp, which includes a horizontally arranged central plate, three cantilever arms fixed to the central plate and evenly distributed in the circumferential direction, and lifting lugs fixed to the central plate. The ends of the cantilever arms are hinged to lifting rods, and the lower ends of the lifting rods are fixedly connected to horizontal support plates for supporting the triangular glass plates. During lifting, the three horizontal support plates support the three sides of the triangular glass plate, reliably fixing the plate and ensuring high lifting safety. It can also lift multiple triangular glass plates simultaneously, resulting in high lifting efficiency. Furthermore, the lengths of the three cantilever arms are adjustable, allowing it to better meet the lifting requirements of triangular glass plates of different sizes and shapes.

[0004] The above-mentioned and existing technologies have the following drawbacks: when multiple glass panels need to be hoisted at the same time, the glass panels will come into contact with each other, causing adjacent glass panels to rub against each other due to shaking during hoisting, which in turn causes scratches on the surface of the glass panels and reduces the practicality of the hoisting fixture.

[0005] Therefore, a lifting clamp with protective function is proposed. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that when multiple glass panels are hoisted at the same time, the glass panels will come into contact with each other, causing adjacent glass panels to rub against each other due to shaking during hoisting, which in turn leads to scratches on the surface of the glass panels. Therefore, a hoisting clamp with protective function is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a lifting clamp with protective function, comprising an installation tube, a crossbeam fixedly mounted on the outer wall of the installation tube, a lifting ring fixedly mounted on the upper surface of the installation tube, a sliding tube slidably mounted on the surface of the installation tube, a connecting rod fixedly mounted on the lower surface of the sliding tube, and several partitions slidably mounted on the surface of the connecting rod.

[0008] The effect achieved by the above components is as follows: through the cooperation of components such as sliding tubes, connecting rods and partitions, when multiple glass panels need to be hoisted at the same time, the partitions can isolate the glass panels, avoid the occurrence of scratches caused by friction between the glass panels, and improve the practicality of the hoisting fixture.

[0009] Preferably, the surface of the connecting rod is slidably fitted with a sliding sleeve, the sliding sleeve is internally threaded with a screw, one end of the screw is rotatably connected to a pressure plate, the connecting rod is provided with a triangular groove at a position relative to the pressure plate, the pressure plate is slidably connected to the triangular groove, and the pressure plate is slidably connected to the sliding sleeve.

[0010] The effect achieved by the above components is as follows: when the screw is rotated, the screw will drive the pressure plate to slide along the inner wall of the triangular groove through the thread. The cooperation between the pressure plate and the triangular groove allows the pressure plate to move downward during the rotation of the screw. The screw moving with the pressure plate will drive the sliding sleeve to move. The movement of the sliding sleeve will squeeze the partition, thereby pressing the partition tightly.

[0011] Preferably, the connecting rod has a regular hexagonal prism structure.

[0012] The effect achieved by the above components is that the connecting rod, which has a regular hexagonal prism structure, can restrict the sliding path of the partition and ensure that the partition can properly support the glass plate.

[0013] Preferably, a rubber pad is fixedly fitted onto the surface of the partition.

[0014] The effect achieved by the above components is that the rubber pad can increase the friction between the partition and the glass plate.

[0015] Preferably, a pin slides through the sliding tube, and the upper surface of the mounting tube has several insertion holes that are compatible with the pin.

[0016] The effect achieved by the above components is that after the pin is inserted into the socket, the socket restricts the position of the pin, thereby restricting the position of the slide tube.

[0017] Preferably, a spring is fitted onto the surface of the pin, and the two ends of the spring are fixedly connected to the pin and the slide tube, respectively.

[0018] The effect achieved by the above components is that when the spring contracts, the pin will automatically insert into the socket with the help of the spring's elastic force, and the spring can prevent the pin from coming out of the socket.

[0019] Preferably, a traction rope is fixedly mounted on the surface of the sliding sleeve, a retaining ring is fixedly mounted on one end of the traction rope, and a magnetic post adapted to the retaining ring is fixedly mounted on the surface of the sliding sleeve. The retaining ring is made of iron.

[0020] The above components achieve the following effects: after the retaining ring is supported between two adjacent partitions, it will maintain a distance between the partitions, thus facilitating the subsequent placement of the glass plate; after the retaining ring is put on the magnetic column, the magnetic column will restrict the position of the retaining ring, preventing the retaining ring from swinging and hitting the glass plate during hoisting.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, through the cooperation of components such as sliding tubes, connecting rods, and partitions, when multiple glass plates need to be hoisted simultaneously, the partitions can isolate the glass plates, preventing them from rubbing against each other and causing scratches, thus improving the practicality of the hoisting fixture.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-4As shown, this utility model provides a lifting clamp with protective function, including an installation pipe 1. A crossbeam 2 is fixedly mounted on the outer wall of the installation pipe 1. A lifting ring 3 is fixedly mounted on the upper surface of the installation pipe 1. A sliding tube 4 is slidably mounted on the surface of the installation pipe 1. A connecting rod 5 is fixedly mounted on the lower surface of the sliding tube 4. Several partitions 6 are slidably mounted on the surface of the connecting rod 5. Through the cooperation of components such as the sliding tube 4, the connecting rod 5, and the partitions 6, when multiple glass plates need to be lifted at the same time, the partitions 6 can isolate the glass plates and prevent the glass plates from rubbing against each other and causing scratches, thus improving the practicality of the lifting clamp. A sliding sleeve 7 is slidably mounted on the surface of the connecting rod 5, and a screw thread is internally connected to the sliding sleeve 7. A pressure plate 9 is rotatably connected to one end of a rod 8 and a screw 8. A triangular groove 10 is provided on the connecting rod 5 relative to the pressure plate 9. The pressure plate 9 is slidably connected to the triangular groove 10 and to the sliding sleeve 7. When the screw 8 is rotated, the screw 8 will drive the pressure plate 9 to slide along the inner wall of the triangular groove 10 by means of the thread. The cooperation between the pressure plate 9 and the triangular groove 10 can make the pressure plate 9 move downward during the rotation of the screw 8. The screw 8 moves with the pressure plate 9 and drives the sliding sleeve 7 to move. The movement of the sliding sleeve 7 will squeeze the partition 6, thereby pressing the partition 6 tightly. The connecting rod 5 has a regular hexagonal prism structure. The regular hexagonal prism structure of the connecting rod 5 can limit the sliding path of the partition 6 and ensure that the partition 6 can properly support the glass plate.

[0031] A rubber pad 11 is fixedly fitted onto the surface of the partition 6. The rubber pad 11 increases the friction between the partition 6 and the glass plate. A pin 12 slides through the sliding tube 4. Several insertion holes 13 adapted to the pin 12 are opened on the upper surface of the mounting tube 1. After the pin 12 is inserted into the insertion hole 13, the insertion hole 13 restricts the position of the pin 12, thereby restricting the position of the sliding tube 4. A spring 14 is sleeved on the surface of the pin 12. The two ends of the spring 14 are fixedly connected to the pin 12 and the sliding tube 4, respectively. When the spring 14 retracts, the pin 12 will automatically insert into the insertion hole 13 with the help of the elastic force of the spring 14. Inside, spring 14 prevents pin 12 from coming out of socket 13. A traction rope 15 is fixedly mounted on the surface of the sliding sleeve 7. A retaining ring 16 is fixedly mounted on one end of the traction rope 15. A magnetic post 17 that matches the retaining ring 16 is fixedly mounted on the surface of the sliding sleeve 7. The retaining ring 16 is made of iron. After the retaining ring 16 is supported between two adjacent partitions 6, the partitions 6 will maintain a distance, which facilitates the subsequent placement of glass plates. After the retaining ring 16 is put on the magnetic post 17, the magnetic post 17 will restrict the position of the retaining ring 16 and prevent the retaining ring 16 from swinging and hitting the glass plate during hoisting.

[0032] The overall working principle is as follows: When multiple glass panels need to be hoisted simultaneously, the retaining ring 16 is first supported between two adjacent partitions 6. Then, the glass panel is placed on the lower partition 6. At this time, the rubber pad 11 will contact the glass panel, increasing the friction between the partition 6 and the glass panel. Then, the retaining ring 16 is removed, and the above operation is repeated to stack the glass panels one by one. The partitions 6 can isolate the glass panels, preventing them from rubbing against each other and causing scratches. Next, the retaining ring 16 is put on the magnetic post 17. The magnetic post 17 restricts the position of the retaining ring 16, preventing it from swinging and hitting the glass panel during hoisting. Then, the screw 8 is rotated. The screw 8 will drive the pressure plate 9 to slide along the inner wall of the triangular groove 10 through the thread. The cooperation between the pressure plate 9 and the triangular groove 10 allows the pressure plate 9 to move downwards during the rotation of the screw 8. The screw 8 follows the movement of the pressure plate 9. The movement of the sliding sleeve 7 will cause the sliding sleeve 7 to move, which will squeeze the partition 6, thereby pressing the partition 6 tightly and making the glass plate in close contact with the rubber pad 11, preventing the glass plate from shaking during hoisting. When it is necessary to hoist glass plates of different sizes, pull the pin 12 upward to disengage the pin 12 from the insertion hole 13. Then, slide the sliding tube 4 along the surface of the mounting tube 1 according to the size of the glass plate. The connecting rod 5 will slide along the sliding tube 4, which will cause the partition 6 to slide, thereby adjusting the position of the partition 6. After the adjustment is completed, release the pin 12. The pin 12 will be inserted into the insertion hole 13 with the help of the spring force of the spring 14. The insertion hole 13 will limit the position of the pin 12, thereby limiting the position of the sliding tube 4. The spring 14 can prevent the pin 12 from coming out of the insertion hole 13. The connecting rod 5, which has a regular hexagonal prism structure, can limit the sliding path of the partition 6, ensuring that the partition 6 can properly support the glass plate. Then, the sling is passed through the lifting ring 3 for hoisting operation.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
